Subject: [PATCH net-next 00/12] net: dsa: vsc73xx: Implement VLAN operations

This patch series is a result of splitting a larger patch series [0],
where some parts was merged before.

The first patch implements port state configuration, which is required
for bridge functionality. STP frames are not forwarded at this moment.
BPDU frames are only forwarded from/to the PI/SI interface.
For more information, see chapter 2.7.1 (CPU Forwarding) in the
datasheet.

Patches 2, 7-9 and 11 provide a basic implementation of tag_8021q
functionality with QinQ support, without VLAN filtering in
the bridge and simple VLAN awareness in VLAN filtering mode.

Patches 3-6 came from Vladimir Oltean. They prepare for making
tag8021q more common. VSC73XX uses very similar tag recognition,
and some code from tag_sja1105 could be moved to tag_8021q for
common use.

Patch 10 is preparation for use tag_8021q bridge functions as generic
implementation of the 'ds->ops->port_bridge_*()'.

Patch 12 is required to avoid problem with learning on standalone ports.
